Abstract

An electric hotplate has a hotplate body in the form of a thin ceramic substrate, to whose bottom surface is applied, e.g. by printing, a thin resistive material film. This resistive material film is covered by a protective coating, which prevents damage. Between the protective coating and the bottom tray of the hotplate is provided a thermal insulating layer. The hotplate has an extremely low thermal capacity, so that rapid preliminary cooking or boiling is possible with low power consumption.

い使用温度しか可能でないという欠点がある。It is already known to provide a thin layer of electrical material on the underside of a glass-ceramic cooking plate and to apply a resistive foil heating element to the underside of this thin layer. The heating foil and the electrical layer are then pressed onto the underside of the glass-ceramic cooking plate by means of elastic devices (German Application No. 27
12881). However, this has the disadvantage that only very low operating temperatures are possible, since the known glass-ceramics become electrically conductive from 300°C.

側面に押しつけられる。It has already been proposed to arrange a thin flexible tube heating body on the lower side of the flat metal cooking plate body (Patent No. 30
3382B). This heating element is pressed against the lower side of the body by means of an elastic element.

この調理板は真価を発揮した。この発明の基本課題は、
特に構造が簡単で且つ製造が容易で、接続負荷を比較的
小さくして極めて短い煮立て時間を保証する、初めに記
載した種類の調理板の提供にある。This cooking board showed its true value. The basic problem of this invention is
The object of the present invention is to provide a cooking board of the type mentioned at the outset, which is particularly simple in construction and easy to manufacture, and ensures very short boiling times with relatively low connection loads.

この課題を解決するために提案されるこの発明の方策は
次のようなものである。即ち初めに記載した種類の調理
板で本体を電気絶縁した熱良導性の材料から成る扁平な
台で形成し、この台の下側面に抵抗材から成る層をとり
つけるのである。The measures of this invention proposed to solve this problem are as follows. That is, a cooking board of the type described at the outset is formed by a flat base made of an electrically insulated and thermally conductive material, and a layer of resistive material is applied to the underside of this base.

その場合本体は、たとえば酸化マグネシウム、酸化アル
ミニウム或いはたとえばＫＥＲ２５０のよう々適当な工
業用セラミック等のセラミックで作るのが有利である。The body is then advantageously made of ceramic, for example magnesium oxide, aluminum oxide or a suitable technical ceramic, such as KER 250, for example.

は殆んどない位小さい。従って煮立ては、大して電気を
消費しないで極めて急速に行われる。It is also advantageous to use silicon nitrides with hardened reaction or forge-pressed silicon nitrides. This material has good thermal conductivity and resists temperature changes very well and has a low coefficient of expansion. Due to the high to sufficient mechanical rigidity, high insulation values and at the same time good heat transfer properties, the body can be made thin, so that the cooking plates made in this way have a small heat capacity that is practically negligible. Boiling therefore takes place very quickly and without consuming much electricity.

抵抗層は特に真空中で蒸着される。しかしスクリーン印

抵抗は所謂サーメツト層から作られる。この層ではガラ
スフリットに白金、ロジウム或いは他の適当な金属を酸
化物の形で粉末にして混入しである。The resistive layer is preferably deposited in vacuum. However, it is particularly advantageous when printed by screen printing methods. The resistor is then made from a so-called cermet layer. In this layer, the glass frit is mixed with powdered platinum, rhodium or other suitable metals in the form of oxides.

温度を感じとるために、同じスクリーン印刷法でもう一

係数をもつ温度従属物質をとりつけることができる。In order to sense the temperature, one or more temperature dependent materials with negative (NTc) or positive (PTO) resistance coefficients can be applied in the same screen printing process.

両方の場合共同時に調理板本体に抵抗層が充分な付着力
で簡単にとシっけられる。In both cases, the resistive layer can be easily attached to the cooking plate body with sufficient adhesion.

この発明の更に別の展開では、抵抗層の抵抗値は横断面
積の縮小によって同調されている。In a further development of the invention, the resistance value of the resistive layer is tuned by reducing the cross-sectional area.

これは特にレーザーを用いて行なわれる。This is done in particular using a laser.

セラミックからできている台を染色しであるのが有利で
ある。こうして、調理板に見て分る外見を与えることも
できる。Advantageously, the base made of ceramic is dyed. In this way, it is also possible to give the cooktop a recognizable appearance.

更に別の展開では、抵抗層を相互に絶縁する個々の領域

域はこうして使用中の調理板の直径の拡大を可能にする
。A further development is to divide the resistive layer into individual regions that are insulated from each other. In this way, the individual areas of the surface of the cooking board also
Combinations of those regions can also be heated separately. For example, the innermost portion can be circular to allow for additional connections to a number of toroidal regions. Those areas thus allow an enlargement of the diameter of the cooking plate during use.

側にのみ載っている市販の調理鍋を使う場合には有利で
ある。According to another feature of the invention, the resistive layer has regions of different electrical loads on its surface. This measure allows the heat emitted by the individual areas to be matched to the cooking needs. For example, the outer area of a round cooking surface can be heated more intensely. This is particularly advantageous when using commercial cooking pots, which normally rest only on the outside of the outer ring of the cooking plate.

この発明のまた別の特徴によれば、それらの領域をリン
グ状或いは円形に構成しである。According to another feature of the invention, the regions are arranged in a ring or circular shape.

ばレーザ法で溶接することもできる。The electrical connection wires are hard soldered to the resistive layer or silver-plated. This is a particularly convenient, space-saving and cheap fixing mode. This is because there is no need for an additional connection terminal at this location. This is because silver plating can be done at the same time as the resistor layer is manufactured. It is also possible to apply a silver-palladium layer as a contact using the same screen printing method and then to solder a metal angle, for example a nickel plate, to this layer. This angle can then be subjected to conventional electrical resistance welding. It is also possible to deposit a nickel layer as a contact in a vacuum and then weld the metal angle to this layer, for example by laser method.

その場合これらの接続のけん引除荷は濡縁の下方に向け
られた側部によって吸収されるのが有利である。Advantageously, the traction unloading of these connections is then absorbed by the downwardly directed sides of the wetted edges.

とも二本のビンをとシつける。これらのピンはトラフに
調理板を固定するのに固定皿又は底板を用いるために設
けである。In order to be able to securely and securely fix the cooking plate to the oven trough, the invention further provides at least two bottles on the downwardly directed side of the wetted edge. These pins are provided for use with a fixing plate or bottom plate to secure the cooking plate to the trough.

台を濡縁に固定するのも極めて簡単である。It is also extremely easy to fix the stand to the wet edge.

場合には特に好都合に形成される。This is because, according to the invention, the heating plate is closely glued into the wetted edge, in particular with a ceramic adhesive. The heating plate is then particularly advantageously designed if the coefficient of expansion of the wetted edge is balanced with that of the heating plate.

更に、抵抗層の領域は扇形又は円環扇形の形を有する。Furthermore, the regions of the resistive layer have a sector-shaped or annular-sector shape.

たとえば通常の調理板がもつ円形は八つの同じ大きさの
扇形によって構成される。For example, the circular shape of a typical cooking board is made up of eight sectors of the same size.

領域を構成する際にそれらの領域は両側面に交互に切込
をもつ。これらの切込は面方向の横断面積を縮小する。One connecting line is then connected to the center of the circle and one to the periphery of the circle. When forming the fan-shaped or annular sector-shaped regions of the resistance layer, these regions have alternating cuts on both sides. These cuts reduce the lateral cross-sectional area.

その場合そのように形成された抵抗層の領域は曲折形状
である。その場合特に、二つの扇形はそれぞれその分離
線に関して相互に対称に構成しである。The regions of the resistance layer so formed then have a meandering shape. In particular, the two sector shapes are then constructed symmetrically with respect to each other with respect to their separation line.

。This has the particular advantage that the winding voltage on both sides of the separating wire is large, so that the potential on both sides of the separating layer is increased in magnitude. This means that the isolation line between each two regions can be made thin enough to allow the method used to attach the resistive layer. As a result, the heat is the same everywhere on the cooking surface.
